Open World Human RP Planning

Id just like to know what kinda setting it is for sure myself?

Is this a fallout scenario minus guns post apocalyptic style - and maybe plus weird phenomena that caused it led to 'magic' and thus 'races/mutations' etc ?

Or is it the latter but everything isn't total ruin just the old world kinda collapsed? (Maybe like horizon zero dawn but with better tech minus guns etc idk)

I'm not sure what thoughts I can give until I'm sure on a picture hm.

But on the gun debate - I'm kinda ehhh on guns bc yeah they don't miss usually since they're well too fast to dodge ? But idk.

Maybe a good solution is like having crossbows/bows instead of gun projectile weaponry since it's basically medieval 'guns' in a way but aren't insta kill / can be dodged.
